Introduction
This Manual contains information on how to install, congure and operate YDTC-13
digital thermometers (hereinafter Thermometer) and YDBC-05 digital barometers
(hereinafter Barometer) intended for use on pleasure crafts.
The Thermometer and Barometer (hereinafter, where the differences are not
critical, Devices) have one digital sensor. Up to 50 devices may be used on a vessel
simultaneously; this limitation is set by the network specication. Data from
the Devices can be displayed on chartplotters, digital navigation instruments, as well
as used by other digital equipment of the vessel.
The Thermometer performs measurements within the range from -55 to +125 °С
(-67..+257 °F), the sensor is placed outside the case on a exible 95cm-long wire
in a sealed stainless steel sleeve and can be used to measure the temperature
of gases and liquids. The wire, if necessary, can be elongated up to 100 meters.
The Thermometer can be congured to display its data as "Air temperature",
"Sea temperature", "Temperature in the refrigerator", "Temperature in the engine
room", etc.
The Barometer is intended for measuring atmospheric pressure within the range
from 300 to 1100 hPa (mbar). The sensor is located inside the device case.
The Barometer identier can be congured so that data from several Barometers
will be simultaneously displayed on a chartplotter.
The Devices are designed for operating in an NMEA 2000 network and
are compatible with a wide range of equipment supporting this protocol. Raymarine
SeaTalk NG, Simrad SimNet, Furuno CAN networks are branded versions
of NMEA 2000 and differ only in the type of connectors. In its devices, Garmin
uses the NMEA 2000 Micro connector which is compatible with the DeviceNet

Micro connector. Our Devices are supplied with different types of connectors,
making it possible to connect them to networks of different manufacturers without
any adapters. The Device model is shown on the case.

Garmin NMEA 2000 Male
To connect to other types of NMEA 2000 networks, a cable adapter is required
(it is not supplied with the Device and must be purchased separately).
According to the specication, an NMEA 2000 network has two terminators
(120-Ohm resistors) connected to the NMEA 2000 bus ends. Device models with
the T index at the end of their names contain a built-in terminator and should be
connected to the network instead of the terminator. This allows a zero-cost connection
of the Devices to existing networks with no free connectors. Please note that according
to the specication, you can not use more than two devices with the T index on one
NMEA 2000 bus.
We thank you for purchasing our Devices and wish you happy voyages!

Warranty and Technical Support
1. The Device warranty is valid for two years from the date of purchase. If a Device
was purchased in a retail store, when applying under a warranty case, the sale
receipt may be requested.
2. The Device warranty is terminated in case of violating the instructions of this
Manual, case integrity breach, repair or modication of the Device without
manufacturer’s written permission.
3. Modication of the Thermometer sensor cable is performed by the user at his own
risk, the warranty does not cover the Device failure in this case.
4. If a warranty request is accepted, the defective Device must be sent
to the manufacturer.
5. The warranty liabilities include repair and replacement of the goods and do not
include the cost of equipment installation and conguration, as well as shipping
the defective Device to the manufacturer.
6. Responsibility of the manufacturer in case of any damage as a consequence
of the Device operation or installation is limited to the Device cost.
7. The manufacturer is not responsible for any errors and inaccuracies in guides and
instructions of other companies.
8. The Device requires no maintenance. Device’s case is non-dismountable. If the
event of a failure, please refer to Appendix A before contacting the technical
support.
9. The manufacturer accepts applications under the warranty and provides technical
support only via e-mail or from authorized dealers.
10. Contact details of the manufacturer and a list of the authorized dealers
are published on the website: http://www.yachtd.com/.

II. Device Connection and Testing
The Device requires no maintenance; calibration of the digital sensors has been
performed by the manufacturer. Therefore, you can set an offset from -10.0 to +10.0
(Celsius for Thermometer or hPa for Barometer) for the sensor readings to align
with readings from other ship equipment (see Section III).
When deciding where to install the Device, choose a dry mounting location.
Avoid places where the Device can be ooded with water, this can damage
it. The Thermometer sensor has a waterproof case made of stainless steel
and is not intended for permanent location in hostile environments such as sea
water. To prevent corrosion, when installing outdoors protect the sensor case with
the help of a coating of paint.
Read the model number on the Device case. If the model name has the T index
at the end (for example, YDBC-05NT), then the device has a built-in terminator
(with resistance of 120 Ohm) and must be connected to the bus instead of an existing
terminator. Different connectors for terminators (blue) and devices (white) are used
in the SeaTalk NG network, which eliminates the chance to err. In networks with
the NMEA 2000 Micro connectors (DeviceNet Micro, Garmin NMEA 2000), devices
are connected to the Female connector on the bus, while terminators are connected
to both Male and Female connectors.
The Device is directly connected to the bus without a drop cable. Before connecting
the Device, turn off the bus power supply. Refer to the manufacturer's documentation
if you have any questions regarding the use of connecting cables, terminators
and connectors:

After connecting the Device, close the lock on the connection to ensure its water
resistance and reliability.
